Answer 1

Explanation:

Here hydrogen is burned in the air or oxygen produces water. Here sulphur is burned in the air to produce sulphur dioxide. Here barium metal and fluorine gas is combined to produce salt barium fluoride which is highly exothermic reaction. Here magnesium oxide is combined with carbon to produce magnesium carbon dioxide.10

Decomposition of calcium carbonate:Calcium carbonate (lime stone) decomposes into calcium oxide (quick lime) and carbon dioxide when heated. ...

Decomposition of potassium chlorate:When heated strongly, potassium chlorate decomposes into potassium chloride and oxygen.

Example – Fe + CuSO4 FeSO4 + Cu.

2K + MgCl2 2KCl + Mg.

AgNO3 + NaCl AgCl + NaNO3.

Zn + CuSO4 ZnSO4 + Cu.

Cu + 2AgNO3 CuNO3 + 2Ag.

Fe + CuSO4 FeSO4 + Cu.

Pb + CuCl2 PbCl2 + Cu.

Cl2 + 2NaBr 2NaCl + Br2.

Zn(s) + Cu2+(aq) → Zn2+(aq) + Cu(s) The oxidation half reaction, in which solid zinc loses two electrons, is.

Zn(s) → Zn2+(aq) + 2e- Notice that in the half reactions we incorporate electrons as a reactant. ...

Cu2+(aq) + 2e- → Cu(s)
